ilus nventionf-rel tjes to chargingffo for enameli'ngjYfurnaces71 anditsprincip'alf object is to provide means for econom-izjng time inchargingenameling furnaces Withf articles-on n fhijch enamel is ,tobebaked. .ln` the 'ordinary practice, venamel jware is, loaded upon a:charging fork Whichwhenl loaded,` vis Y insertedV into 'the "furnace,`the material de,-r posited' thereinr V,andl the fork Withdrawn.V `Whenthe articles have been leftinthefurnace for a sufficient time tobake theenamel thereon, the forkisretnactedand thelist,ar-y ticlesfremoyedfrom`I the furnaceQ Thereafter they are removedfroiiji. the forklfandafresh Z supply loadedthereon'and inserted as be-A 5 takes time, 'fuelis lWasted,l and `-While the baking process is going onythe fork is idleand time of the Workmen is Wasted.

f l have overcome the objectionable features by providing a double forkby means of which at least one fork is practically always in use, andthe Workmenls time is continuously employed in loading or` unloadingyone of the forks; the furnace also being continuously in use in bakingthe enamel upon the articles. `With these ends in View, this inventionconsists in a pair of chargingv forks,V

eachy operable lindependently of the` other,`

and both -rnounted "upon Wheels;A whereby o either may be broughtintolichargng position f before a furnace door, While the other isdisposed-at one side thereof, Vwhereby it mayL be loaded andunloadedwhile -the baking process is being carried on. The invention 15further consists inV the severaljnovel features hereinafter fully setVforth and claimed. Y

The invention is clearly 'illustrated inv the accompanying drawings, inWhich:

They track bars 13, areapprorrimatelyas. high as;y the piersal`7 and in the operation of the deil vice one set of tra-ck bars, is brought directly in front of the dooropening a, and piers al, inV position to enable the associated ,fork tobe inserted into theV furnace to deposit articles on the piers therein7or to remove them therefrom. 9 Theforks may-be ofv .any suitable formand construction, and may be hand or power operated. The forks shownillustrateone form of manually operated forks; they are similar inconstruction and a description of manipulated. Cross barsla atthe rearend A Work support isr provided for carrying'.

which are adapted to rest on the fork bars A16 of each fork, and uponthe piers a1, when placed in the furnace.

on the railsY until `a loaded fork is brought directly in front of thefurnace door opening; the door of the opening is then raised and thefork is moved forward into the furnace, and the work support, andarticles carried thereby, are deposited on the piers in the furnace inthe usual manner.`

The fork is then withdrawn from the furnace. rvVhile the baking processis being carried on, the other fork is being loaded with articles to bebaked, and when thev articles in the furnace are finished, the furnacedoor is opened, the empty fork is inserted into the furnace, underneaththe work support, the handle depressed, and the work support, andarticles carried thereby, are

lifted from the piers, and the fork is withdrawn from the furnace. Thecarriage is thereupon moved over bringing the freshly loaded forkdirectly in front of the furnace y door opening and the fresh supply ofkarticles is deposited in the furnace, as -above del y the furnace may bekept in continuous opera- Y In operation, the fork carriage is movedalon ftion, and there is no loss 'of time between and during the heats.l l

More or less variation of the exact details of construction is possiblewithout departing'from the spirit of this invention; I desire,therefore, not` to limit myself .t'o the exact forni of the constructionshown and described, but intend, in the following claims, to pointout'allof the invention disclosed herein.

I claiml as new, `and desire to secure by Letters Patent:

y l. Charging means naces, comprising a traveling, wheeled carriage, twowidely spaced sets of track bars securedv on .said carriage, land twofork frames 'mounted on rollers thatV travel on said track bars, eachfork being movable independent of theother, and there beingfree andvunobstructed loading and unloading passages between ,said sets ofytrack bars, and between said lfork yframes, whereby either fork frame`may be loaded and unloaded fromv either side;

2. A Ycharging fork` for` enameling furnaces, comprising apair of sunkenrails, a fork carriage having wheels traveling on said`rails,.two widelyspaced sets of track bars securedon said carriage, and two charg- V ingforks mounted to travel 'on said track bars, there being free `andunobstructed loadingjand unloadingpassageways between said setsl oftrack bars, and between said charging forks, whereby either 'fork Ymaybe loaded and unloaded fromk either side.
